The New SA-20 Semi-Automatic 20 Gauge Shotgun by Mossberg International: Perfectly balanced, fast handling, lightweight and just as important, easy on your wallet. This soft shooting, gas-operated shotgun is available in two models to fit all size shooters. The SA-20 is fitted with a standard 14” length of pull (LOP) synthetic stock and forearm while the SA-20 Bantam features a shortened 13” LOP. The gas system on this reliable wingshooter vents excess gases to aid in recoil reduction and helps in eliminating stress on the operating components. This is one fun shooting, goes anywhere, do anything kind of gun, with the built-in features normally found on shotguns costing twice the price. Whether your idea of fun is busting clays on the range, chasing small game or hunting doves, the SA-20 and SA-20 Bantam models fit the bill.
